installtion fails

Hi,
I just tried to install your Easy Yii2 CMS after having done all configuration steps,as described.
After I had fill in Root password, Admin E-mai, Robot E-mail, Recaptcha Key, and finally Recapta Secret, I got error: 404 – out of framework yii2.0!
So, your project online is well done, but installtion locally fails, ‘cause it seems to be incomplete!
Orders like yii migrate or init fail,too!
